Well, now that I’m over my initial pique and back to my usual rational state
, I will actually make a positive post. I am looking forward to the next update with the bugs fixed. I did go ahead and update to iOS 13.1 on my go to phone and my old iPad Air 2. The old CC was not affected (works like always)and after updating to the latest Calibre, connecting via content server or wireless is working fine in both old and new CC apps.
